# std::regex_iterator<BidirIt,CharT,Traits>::operator==,operator!=

From cppreference.com
< cpp‎ | regex‎ | regex iterator

bool operator==( const regex_iterator& rhs ) const; | (1) | (since C++11)
bool operator!=( const regex_iterator& rhs ) const; | (2) | (since C++11) (until C++20)

Compares two `regex_iterator`s.

The `!=` operator is synthesized from `operator==`. | (since C++20)

### Parameters

rhs | - | a `regex_iterator` to compare to

### Return value

For the sake of exposition, assume that `regex_iterator` contains the following members:

- `BidirIt begin`;
- `BidirIt end`;
- const regex_type *pregex;
- std::regex_constants::match_flag_type flags;
- std::match_results<BidirIt> match;

1) Returns true if *this and rhs are both end-of-sequence iterators, or if all of the following conditions are true:

- begin == rhs.begin
- end == rhs.end
- pregex == rhs.pregex
- flags == rhs.flags
- match[0] == rhs.match[0]

2) Returns !(*this == rhs).
